'hpPostProcessing.bundle' malware?

I have the same problem in trying to print from HP Color LaserJet 2025 with the alarm message: “hpPostProcessing.bundle” will damage your computer. I have downloaded printer software 5.0 but this has not solved the problem. This seems to have occurred after the latest software update.

Usually problems like this are due to old certificates that expire and hardware companies with poor support.

Apprently this certificate did not expire, it was revoked by apple.

Then you shouldn't use it. Apple would not have revoked a certificate without good reason.

There's a workaround here: Sudden Problem with Printing

it's malware possible. maybe apple team support for you. you must contact Apple team

good luck başvuru tarihi

I think you will need to actually delete the old unsigned driver as described above.

When you choose to use the AirPrint driver over the "standard" Mac driver, the disadvantage is:

you are discarding any possible use of Printer special features that could have been specified in the Printer dialog box.

Some printers can do built-in duplexing, alternate paper trays, image rotations or landscape/portrait, different paper sizes, shrinking/enlarging, different grayscale or color options, draft mode, and more.

the advantage is:

it prints the same way as your phone.

I have been working on this problem since last night. It worked earlier in the day. UGH! I thought my printer cable went out and bought a new one.

APPLE, I am a teacher and bought a MAC in March to support my Distance Learning. You can have it back if I have to buy a printer, too.

Did it work? If you look in the FTP directory

ftp://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/ 

suggested by SS_MedPhoto, the date of the file

hp-printer-essentials-S-5_14_8_4.pkg 

is 10 July 2020, not yesterday.

I just installed the link suggested by SS_MedPhoto above (for hp-printer-essentials). I am now getting the error: "Matterhorn.framework" will damage your computer....

BUT after clicking 'ok' on that error message about a dozen times... it finally printed!

Fingers crossed this is now fixed!

Same problem with my HP2015dn printer ... just won’t print, MacBook ‘finder’ doesn’t even show its connected it’s not an AirPrinter - It’s connected with a Ethernet cable ... so I’m stuck for the moment/- has anyone got a fix ???

I used CUPS to drive a HP Laser 4M till it finally died around 10 years back, replaced it with the HP 1320 we are using now. With the price of toner carts you'd think HP would have an incentive to keep their software up to date. Using the HP Easy Start, it fails to find drivers for the 1320 and a search on HPs website list only OS9 drivers.

The file in question (whether the ftp or http link) is widely reported as ineffective. The System updates is still ineffective (Command+R notwithstanding).

The files recommended here are time stamped in June with the exception of one (...ASU/Hewlettpackardprinterdrivers...) which is dated 6th October. (i.e. not the one pointed to above)

It seems surprising to me that in June, HP had a file that was going to fix a problem that had not yet been caused and a fault that was actually going to be within within the OSX security signing system rather than anything to do with the drivers themselves.

Well I have already fixed the issue and am not going to install another fix on top of it. Especially given the facts that there is no comment from Apple, no consistent comment from HP and mixed messages from people who have tried the 'fix' you are reporting.
